Hembased Launches Cold Compostable Filament from Palm Leaves
Dutch firm Hembased has introduced a new 3D printing filament derived from palm leaf waste, aiming to provide a cold compostable and bio-based alternative to conventional materials.
Dutch company Hembased has announced the launch of a new 3D printing filament that is cold compostable. This means the material is designed to fully decompose in a standard home compost bin at ambient temperatures, typically between 20-30°C, within a year, leaving behind no harmful residues. This differentiates it from industrially compostable materials that require specialized high-temperature facilities.
The new filament is produced from palm leaf byproducts, which Hembased states are sourced from agricultural waste. The company claims to be the first globally to offer a cold-compostable, bio-based filament alternative. However, other companies like ColorFabb, Phanbulous, Ecogenesis EcoFab, Regen, and Loopha have previously introduced similar materials.
Hembesed highlights the challenge of balancing print performance with a responsible end-of-life solution, emphasizing that their filament can become a nutrient source in biological systems after its functional life. The palm leaves used are gathered as waste that might otherwise be burned, dried, and ground into a powder. This powder is then processed into a granulate called HemCell, which is used to manufacture the filament.
The company is seeking research partners to collaborate on future projects, particularly those interested in end-of-life solutions and palm oil-related materials. The filament is available in natural hues and is priced at approximately €32 per kilogram.
The introduction of cold compostable filaments like Hembased's aligns with the growing demand for sustainable materials in additive manufacturing. This development is crucial for reducing the environmental footprint of 3D printing, offering a circular economy approach where printed objects can safely return to the biosphere, potentially reducing landfill waste and promoting responsible material lifecycles.
